Retain producer-owned compiler output and cleanup markers through xcrun
resolution and native failure projection. Keep physical preparation failures
primary and preserve separate command deadline classification for interrupted
preparation. Omitted output facts stay unknown; client close does not resolve
foreign helper cleanup. Include CLI failure output in native regression reports.
Validation: 87 focused tests passed. Broader 140-file run passed 1483 tests,
skipped 109, and exposed three pre-existing deep-provider selection failures
tracked in #4555. Static checks passed. Compiler faults use controlled Node
fixtures; native Swift compiler faults and Windows execution were not verified.
Other command consumers still need preparation-fact propagation.
inspect-macho projected an empty Mach-O segment or section name as the
display label "unknown", so an exhaustive segment inventory for an
ordinary MH_OBJECT reported a segment literally named "unknown" while
the raw LC_SEGMENT_64 field showed "". Object files place every section
in one unnamed segment, so the empty name is a source value. Segment and
section names are now reported exactly as observed.
Fixes#3875
